Heaven's Protection. It's Noelle's generated skill upon achieving the Glimpse of her Transcendent Pathway. It's different from the skill that one would naturally acquire upon completing their Mortal Pathway.
I remembered the girl coming to me saying that it's something that is a very useful passive skill with one downside. It will only be triggered if ever she is faced with a fatal danger. In short, it's a life-saving skill that not everyone could have.
When it gets triggered, it would use not only her Source Energy reserves but also the surrounding inherent Source Energy to protect her from dying in a swift fatal strike.
It's still possible to fail if the fatal strike came from an insurmountable entity with Source Energy so thick that it would be impossible to nullify the damage. For example, a Sage.
For the Bonds of Serendipity to pull that out at my moment of demise, it's kind of laughable how lucky I became.
